New to this Forum with alignment issues

Hello, my name is Jay. I am the proud owner of a 2020 SR5 4×4. Purchased my Tundra brand new and love doing my own upgrades. I've learned alot along the way. Used spacers, then Bilstien 5100 and now an Icon stage 6. The Icon set up is amazing.
After we completed the upgrade I aligned the front end as best I could using the Icon UCA and a torpedo level but I did take it to an alignment shop to get it professionally aligned. They told me they could not get it aligned properly. I even told the tech that I put in adjustable UCA's. Theywere trying to get everything zero
My Tundra is lifted 3" in the front and 1.5" is the rear. Running 33 ×12.5x20 toyo AT. I don't know the offset.
Hoping this forum can give some alignment specs. I might be taking it into an offroad shop but I'm always skeptical. I just don't feel the alignment shop I took it to was helping me get all the benefit of the new suspension upgrades.

With billet arms, you have a ton of adjustment. It is typically recommended to utilize a shop that focuses on off-road as they are typically more versed in these adjustable arms. As for spec, ICON develops around OEM specs, so getting to that goal should be very doable.
